To date very few studies with small sample size have compared peroral esophageal myotomy (POEM) with the current surgical standard of care, laparoscopic Heller myotomy (LHM), in terms of efficacy and safety, and no recommendations have been proposed.To investigate the efficacy and safety of POEM compared with LHM, for the treatment of achalasia.The databases of Pubmed, Medline, Cochrane, and Ovid were systematically searched between January 1, 2005 and January 31, 2015, with the medical subject headings (MeSH) and keywords “achalasia,” “POEM,” “per oral endoscopic myotomy,” and “peroral endoscopic myotomy,” “laparoscopic Heller myotomy” (LHM), “Heller myotomy.”All types of study designs including adult patients with diagnosis of achalasia were selected. Studies that did not report the comparison between endoscopic and surgical treatment, experimental studies in animal models, single case reports, technical reports, reviews, abstracts, and editorials were excluded.The total number of included patients was 486 (196 in POEM group and 290 in LHM group).There were no differences between POEM and LHM in reduction in Eckardt score (MD = −0.659, 95% CI: −1.70 to 0.38, P = 0.217), operative time (MD = −0.354, 95% CI: −1.12 to 0.41, P = 0.36), postoperative pain scores (MD = −1.86, 95% CI: −5.17 to 1.44, P = 0.268), analgesic requirements (MD = −0.74, 95% CI: −2.65 to 1.16, P = 0.445), and complications (OR = 1.11, 95% CI: 0.5–2.44, P = 0.796). Length of hospital stay was significantly lower for POEM (MD = −0.629, 95% CI: −1.256 to −0.002, P = 0.049). There was a trend toward significant reduction in symptomatic gastroesophageal reflux rate in favors of LHM compared to POEM group (OR = 1.81, 95% CI: 1.11–2.95, P = 0.017).All included studied were not randomized. Furthermore all selected studies did not report the results of follow-up longer than 1 year and most of them included patients who were both treatment naive and underwent previous endoscopic or surgical interventions for achalasia.POEM represents a safe and efficacy procedure comparable to the safety profile of LHM for achalasia at a short-term follow-up. Long-term clinical trials are urgently needed.
In obese patients with NASH, adiponectin receptors are underexpressed in visceral fat-as a likely correlate of obesity-but overexpressed in liver, possibly as a compensatory response to hypoadiponectinemia, and positively associated with liver damage.
Hypopharyngeal and cervical esophageal tumors represent 5-10% of all esophageal neoplasms and are challenging for both surgeons and oncologists, because the choice of the adequate therapeutic strategy is not clearly defined and therefore difficult. In fact, although surgical treatment represents the gold standard of therapy, chemo-radiotherapy, previously used as adjuvant treatment, has been more recently adopted with curative intent, leaving to surgery a salvage role only. When surgery is required it is advisable to reduce patients' trauma. The present study reports on a personal technique for minimally invasive pharyngo-laryngo-esophagectomy and reconstruction with the whole stomach. We use a laparoscopic approach for mobilization of the stomach, transhiatal esophageal dissection and to follow transhiatal gastric transposition to the neck combined to a cervicotomy to perform pharyngo-laryngectomy, proximal esophageal mobilization, and pharyngo-gastric anastomosis. We performed this technique on four patients with recurrent disease after initially curative primary chemo-radiotherapy. Mean operative time was 345 min (range: 300-384). There were no intraoperative complications. All patients were extubated immediately after the operation and were managed in postoperative care unit for a mean time of 10 days (range: 7-12). Enteral nutrition was begun on post-operative day (POD) 1. The nasogastric tube and drainages were removed on POD 11, and patients immediately started oral nutrition. One patient had a TIA (transient ischemic attack) on POD 2. All patients were discharged within 20 days (18-20). Initial experience with this minimally invasive technique in selected patients is encouraging because it seems to minimize postoperative complications and allows early rehabilitation.
The purpose of this retrospective study was to analyze our results after laparoscopic repair of giant hiatal hernias with direct closure of the hiatus, since the reports document a radiological recurrence rate as high as 42%. Various studies have shown that laparoscopic hernia repair is safe and effective, and carries a lower morbidity than the open approach, but the high recurrence rates still being reported (ranging from 10 to 42%) have prompted many authors to recommend using a prosthesis. This is a report on the follow-up of 38 patients with type III and IV hiatal hernia who underwent laparoscopic repair with direct hiatal closure without the aid of meshes. From January 2000 to March 2010, 38 patients with III and IV hiatal hernia were treated at the Surgery Division of Cisanello Hospital in Pisa. Data were collected retrospectively and included demographics, preoperative symptoms, radiographic and endoscopic findings, intraoperative and postoperative complications, postoperative symptoms, barium X-ray and follow-up by medical examination and symptoms questionnaire. The sample included 12 males and 26 females, between 36 and 83 years (median age 62) with 26 type III (68.4%) and 12 type IV (31.6%) hernias. There were no conversions to laparotomy and no intraoperative or postoperative mortality. A 360° Nissen fundoplication was performed in 22 patients (57.9%) and a 270° Toupet fundoplication in 16 patients (42.1%). One patient had intraoperative complications (2.6%), and postoperative complications occurred in another three (7.9%). The follow-up was complete in all patients and ranged from 12 to 88 months (median 49 months). Barium swallow was performed in all patients and recurrence was found in five patients (13.1%); three of these patients (7.9%) were asymptomatic, while two (5.2%) were reoperated. All 38 patients' symptoms improved. Judging from our data, the recurrence rate after laparoscopic giant hiatal hernia repair with direct hiatal closure can be lowered by complying with several crucial surgical principles, e.g., complete sac excision and appropriate crural closure, adequate esophageal lengthening, and the addition of an antireflux procedure and a gastropexy. We recorded a radiological recurrence rate of 13.1% (5/38) and patient satisfaction in our series was quite high (92%). Based on these findings, the laparoscopic treatment of giant hernias with direct hiatal closure seems to be a safe and effective procedure.
Esophageal inflammatory fibrous polyps are extremely rare benign neoplasms. The manuscript illustrates a case of a man complaining of pyrosis and gastroesophageal reflux symptoms. Diagnostic work-up showed an expansive lesion of the distal esophagus simulating malignancy but with negative, repeated, multiple biopsies. The considerable size of the lesion, and the suspicion of a malignant tumor because of the presence of ulceration, indicated esophagectomy with extensive lymphadenectomy and intrathoracic esophagogastroplasty. The diagnosis of inflammatory polyp of the esophagus was achieved postoperatively. The Discussion deals with a review of the literature and considers the performed operation a good choice considering the hypothesis of a malign neoplastic evolution of this lesion.
